- mode variable: replaced hex format with binary to make it more readable, if compared with bit tables in the 32U4 manual - prescale variable: replaced uint8_t with uint16_t data type (fixes bug, which did not allow frequencies < 492Hz)
Revised by MacTester57 to allow correct PWM frequencies (confirmed with oscilloscope). To allow 123Hz PWM frequency, I had to clean out a bug inside the. The fan runs smoother with it and the waveform looks much better. Added a 4.7uF cap across the fan, in parallel with the flyback diode. replaced the 220R pull up resistor with a 1K, because it ran out of spec (0.66W).

The following changes were done in the PWM controller: System Tools downloads - smcFanControl by Henric Holtmann and many more programs are available for instant and free download.
The touch sensor readings are much more stable now and it seems that the touch sensors are usable now. Power transistor runs a b it cooler (will most likely use a BD438) So I've decided to change the fan PWM frequency to 123Hz. The frequencies are: CPU 50 - 186Hz, HD 83 - 215Hz, Case ? - 168Hz. It seems, that the tach signal is pulled up to 3.3V through the logic board. The tach signals produce a nice, clean 3.3V square wave. I did expect, that they are driven in PWM mode, but not with such a low frequency. Just to let you know: I'm just doing some additional investigations on how the Apple fans work: NOTE: The diagrams were removed See here for final diagrams I have been working on the GND plane, and have separated the audio section from the rest of the fan control and microprocessor. So the redesign of the SMC board continues Size is now 85mm x 65mm I have had to move a lot of pins to make use of the three available Interrupt pins. My main task left is to get the WTV020 sound module to work, and integrate and test with relay (input side), and PAM amplifier. I have committed to producing a SMC board with these features (no more LM317). With the RPM feedback from fans tested, and utilising MacTesters confirmed PWM fan controller. you can also "grep thermal" if you are only interested in that.Building a CustoMac Hackintosh: Buyer's Guideĭouble ret = fan1RotationCount /2L *1000L * 60L / ( millis() - fan1TimeStart ) ĭouble ret = fan2RotationCount /2L * 1000L * 60L / ( millis() - fan2TimeStart ) You will notice the frequency details and also some thermal info. : SYSCALL XD 1GBPAGE EM64T LAHF LZCNT RDTSCP TSCI 7_features: RDWRFSGS TSC_THREAD_OFFSET BMI1 AVX2 SMEP BMI2 ERMS INVPCID FPU_CSDS MDCLEAR IBRS STIBP L1DF SSBD : FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 FMA CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC MOVBE POPCNT AES PCID XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C Or thermal / temperature details only? sysctl -a | grep thermal (but apple maybe removed the details from this to just numbers 0 or 1?) sysctl -a | grep cpu | more sudo powermetricsĪnd at the bottom you will see the following.
